Go with SQL Server Driver Unable to Connect Successfully: Login Fails

Using Go with Microsoft SQL Server driver can present challenges. Here's an overview of the issue and its resolution steps:

Issue:

Upon executing db.ping() with the go-mssqldb driver, you encounter the error "login failed for user 'sakhaloo'". Simultaneously, using SQL Server Management Studio to open the database with the given username and password fails, resulting in the error "A connection was successfully established...but an error occurred during login."

Resolution Steps:

Ensure Proper Driver Installation: Download and extract the go-mssqldb driver package from its GitHub repository, ensuring that the files are placed in the specified directory (C:Gosrcgithub.comdenisenkomgo-mssqldb).
Check SQL Server User and Permissions: Verify that the user 'sakhaloo' exists as an SQL Server user with the appropriate permissions to the intended database. Ensure that the user is granted access to the database through roles or explicit permissions.
Enable TCP/IP Connection: Check if TCP/IP is enabled for SQL Server's protocols. Navigate to SQL Server Configuration Manager, locate Protocols for MSSQLSERVER, and ensure that TCP/IP is enabled. Restart the SQL Server service after making these changes.
Disable SSL Encryption: For SQL Server 2008 and 2008 R2, disable SSL encryption as it can interfere with logins. Install the Service Pack and cumulative updates mentioned in the github repository's documentation.
Review SQL Server Logs: Examine the SQL Server logs in the ERRORLOG file for any error messages that shed light on the login issue. Look for mentions of authentication failures or server configurations that prevent SQL Server authentication.
Grant permissions to the SQL Server user: Use SQL Server Management Studio to grant necessary permissions to the created SQL Server user for connecting to the database and performing required operations.

By following these steps, you can address the login issues encountered with the go-mssqldb driver and successfully connect to and access the SQL Server database.

Go Binary Encoding/Decoding: A Practical Guide with ExamplesMay 07, 2025 pm 05:37 PM

Go's encoding/binary package is a tool for processing binary data. 1) It supports small-endian and large-endian endian byte order and can be used in network protocols and file formats. 2) The encoding and decoding of complex structures can be handled through Read and Write functions. 3) Pay attention to the consistency of byte order and data type when using it, especially when data is transmitted between different systems. This package is suitable for efficient processing of binary data, but requires careful management of byte slices and lengths.

Implementing Mutexes and Locks in Go for Thread SafetyMay 05, 2025 am 12:18 AM

In Go, using mutexes and locks is the key to ensuring thread safety. 1) Use sync.Mutex for mutually exclusive access, 2) Use sync.RWMutex for read and write operations, 3) Use atomic operations for performance optimization. Mastering these tools and their usage skills is essential to writing efficient and reliable concurrent programs.

Benchmarking and Profiling Concurrent Go CodeMay 05, 2025 am 12:18 AM

How to optimize the performance of concurrent Go code? Use Go's built-in tools such as getest, gobench, and pprof for benchmarking and performance analysis. 1) Use the testing package to write benchmarks to evaluate the execution speed of concurrent functions. 2) Use the pprof tool to perform performance analysis and identify bottlenecks in the program. 3) Adjust the garbage collection settings to reduce its impact on performance. 4) Optimize channel operation and limit the number of goroutines to improve efficiency. Through continuous benchmarking and performance analysis, the performance of concurrent Go code can be effectively improved.

Error Handling in Concurrent Go Programs: Avoiding Common PitfallsMay 05, 2025 am 12:17 AM

The common pitfalls of error handling in concurrent Go programs include: 1. Ensure error propagation, 2. Processing timeout, 3. Aggregation errors, 4. Use context management, 5. Error wrapping, 6. Logging, 7. Testing. These strategies help to effectively handle errors in concurrent environments.
